Be it known that I, JO N B. IIADAWAY, a citizen of the United States,residing at Brockton, in the county 'of Plymouth and State ofMassachusetts, have invented certain new and useful Improvements inMachines for Operating upon Welts of Boots and Shoes; and I do herebydeclare the following to be a full,-clear, and exact descri tion of theinvention, such as will enab'e others skilled in the art to whichitappertains .to make and use the same. a

The present invention relates to machines for operating upon welts ofboots and shoes. The object of the present invention is to provide anefficient machine of simple construction by which av series of slits canbe formed in a welt in a certain and satisfactory manner, to prepare thewelt so that it can be easily and quickly beaten out fiat.

- With this object in view, the invention consists in the devices,combinations, and

arrangements of parts hereinafter described and claimed, the advantagesof which will be obvious to those skilled in the art from the followingdescription.

The invention is intended primarily as an improvement in welt beatingmachines which are used in the manufacture of welted shoes to beat outthe welt after attachment to the shoe to cause it to lie flat insubstantially theplane of the insole. Certain features of the invention,however, are equally applicable to machines which do not act to beat outthe welt.

Certain features of the invention are also applicable to machines foroperating on a we tor welt strip before being attached to ashoe. i

the accompanying drawings, in which is I illustrated a machine forslitting and beating out welts embodying 'the invention in its preferredform. Referring to the drawings, Figure 1 is a view in side elevation ofthe machine,

Fig" 2 is a view in front elevation and Fig. 3 is a plan view thereof;Figs. 4 and 5fare views 111 side and front elevation of the welt beatinghammer and Figs. 6 and 7 are top and bottom plan views thereof; Figs. 8,9, and 10 are views in front elevation, Ian, and

side elevation of a work support a apted to support and guide a weltbefore being applied to a boot or shoe; Figs 11, 12, and 13 are views inend. elevation, plan, and side elevation of one 'form of welt slittingknife, the knife illustrated being that illustrated in Figs. 1, 2, and 3and being adapted to form slits in the welt obliquely disposed to thesur face of the welt; Figs. 14, 15, and were views in plan, endelevation and side elevation of amodified form of knife; Figs. 17, .18,and 19 are views in end elevation, plan, and side elevation of a weltbefore being a plied to a boot or shoe provided with slits isposed at,

rig-ht angles to the surface of the welt; and Figs. 20', 21 and 22 aresimilar views of a 'welt provided with slits disposedobli uely to thesurface of the welt; Figs. 23 and 24 are face and ed e views of the camdisk, and Fig.- 25 is a deve opment of the cam disk.

2 indicates the cam shaft journaled in bearings'in the rear portion ofthe machine frame, rovided-at one'end with fast and loose pul eys 3 and4 and having secured thereto between its bearings a cam disk 5.

At the front of the machine frame is a work support 6 which is mountedupon a for:

wardly projecting arm 7 of the frame so as to be adjustable horizontallyby means of a bolt 8 passing through a slot in the arm 7 and screwinginto the work support. The forward end of the Work sup ort is shaped toenter the crease between-t e upper and the welt of a weltedshoe and tosupport the welt on its upper surface, the forwardend of the worksupport by contactwith the bottom of the crease between the upperand'the welt serving as a guide for the shoe being operated upon.

l The lever 10 is provided intermediate its ends with two downwardlyprojecting lugs'between which a block 11. is received and to nwhich thelever is pivoted by means of. a

pivot pin 12 passing through the downwardly projecting lugs of the leverand throughtheblock. The block 1 1 is secured t9 orformed integral witha vertical stud 13 mounted to rotate in suitable bearings inthe frameofthe machine and held from vertical movement by means of'locking nuts14 upon the lower screw-threaded end of the stud;

out and feed the welt as will be hereinafter described. The cylindricalshank of the plunger 9 is mounted to slide in bearings in the forwardend of the lever 10 and is held from rotation by means of a key 20 onthe enlar ed lower end of the shank of the plunger an a cooperatinggroove in the lever. The shank of the plunger extends above the end ofthe lever 10 and at its u )per end is pro- 'vided with a split nut 21having a screwthreaded engagement therewith and being clamped thereto bymeans of a clamping bolt 22. A coiledspring 23 surrounds 'the shank ofthe plunger and is inter osed between the u per end of the recess ormedin the end of t e lever 1-0 to receive the spring and the shoulderformed b the enlarged lower portion of the shank so that the plunger isyieldingly supported on the lever. Ihe downward movement of the lungerunder the influence of the spring 23 is 'mited by the nut 21, theposition of which on the plunger can be adjusted as The Welt slittingknife is indicated at 24. The knife is provided with a flat shank which,is secured by means of a clamping bolt-25 in a socket in an arm 26projecting laterally from a slide 27 mounted to reciprocate inhorizontal guideways on aplate 28 secured to the frame of the machine.The rear end of the slide 27 is provided with a roll or studwhich vdisposed to the surface of the engages a cam groove 29 in one face .ofthe cam disk 5. The arrangement, of theknife 24 and slide 27 is suchthat the knife reciprocates transversely to the line of feed 1nsubstantially the plane of the welt and the cutting blade of the knifeis so arranged with relationto the upper surface of the work support 6upon whic the welt is supported that the slits formed in the welt by-theknife ex-' tend partially through the welt from one surface toward theother and are obliquely welt. In order to vary the depth of the slitsthe knife 24' is adjusted vertically and as a means for effectingsuchadjustment the plate 28 in 'which the slide 27 is mounted is providedwith a guide groove which is engaged by a guiding projection on theframe of the mawhich engages the upper and lower edges of theslot. Theplate28 is clamped to the frame by means of the bolts 30 and 31 and byloosenin the bolts and rotating the eccentric 32 t e date can be raisedor lowered to adjust the nife to cut slits of anydesircd de li th.

he operation of the machine above de scribed is as follows :-S'tartin'gwith the part inthe position indicated in Figs. 1, 2, and 3 in whichposition the plunger 9 is down and at the limit of its movement to theright as viewed in Figs. 2 and 3 as the disk 5 rotates in the directionindicated by the arrow the lever 10 is actuated by the cam groove 18 tomove the plunger 9 to the left, feedin the welt over the support 6; Atthe end of the feeding movement and while the welt is held clampedbetween the plunger and work support the knife 24 is advanced by theaction of the camgroove 29 and caused to cut a slit in the welt. Theknife is arranged in line with the lunger and in order to allow theknife to sllt the welt the plunger is providedwith a recess 33 in itsworking face to receive the knife. During the cutting stroke of theknife thewelt is held clamped between the plunger and work support andis thus supportedagainst the thrust of the knife. In'order to enable theplunger to engage the welt and feed it with certainty, its lower faceiscorrugated as indicated in Figs. 4, 5,

and 7. After the slit has been formed in the welt the lever 10 isactuated by the spring 19 to raise the plunger from the welt and isactuated by the cam groove 18 to return the plunger to its extremeposition at the right,

these movements taking place simultaneously so that the plunger movesdiagonally upward. At the same time the cam groove 29 acts to withdrawthe knife fromthe welt. By-causing these movements to take placesimultaneously instead of successively, the time required for thesemovements is decreased and the speed of the machine is correspondinglyincreased. The lever 10 is then actuated by the cam surface 17 to bringthe plunger 9 1n contact with the welt and is actuated by the cam groove18 to cause the plunger to again feed the work and to raise the plungerand return it to its extreme position at the right. I The lever 10 isthen again actuated by the cam surface 17 to bring the lunger in contactwith the welt, thus comp eting a cycle of operations of the machine. 1

- It will be noted that two" welt beating and feeding movements areimparted to the plunger. for each slitting movement of the 'nlfe, theknife being actuated to slit the welt at the end of every alternatefeed.

movement I consider it preferable to so actuate the plunger and knife asthereby a short feeding movement can be imparted to the welt and theworking face of the plunger which is wider in the direction of feed thanthe length of each feed movement is caused to act upon each ortionof thewelt a plurality of tunes. A so the shoe is more easily guided than whena long feed movement is imparted to the plunger and no difficulty isexperienced in kee ingthe shoe in proper position while the p unger isacting upon the welt at the toe portion of the shoe. It will be obvious,however, that by providing suitably shaped cams a single feedingmovement may be imparted to theplunger for each movement of the weltslitting knife,

or that if desiredthree or more feed movements may be im arted to theplunger for each movement 0 the Welt slitting knife.

The slits formed in the welt by the slitting knife extend through thatportion of the welt which wohld otherwise resist the strain to which'the welt is subjected-during the beating out operation. The grain sideof the welt which is not cut .is easily stretched so that the beatingout operation is performed in a satisfactory manner by subjecting thewelt butonce to the operation of the machine.

The advantages secured by forming slits in the welt which arediagonally-disposed to the surface of the Welt Wlll be obvious from anins ection, ofF-igst'20, 21 and 22. In these gures 34 indicates a weltstrip before being applied to a boot or'shoe provided with slits 35diagonally disposed with relation to the surface of thewelt.

From these figures it will be evident that when the outer edge of thewelt is stretched the portions of. the welt above and bglow the slitswill slide over each other and can be compressed during the welt beatingoperation soithat no open slots will be left in the. welt. The form 0the slit 35 illustrated in Figs. 20, 2'1 and 22 is that produced by theslitting knife illustrated in Figs. 11, 12 and 13. I, It will be seenthat thebottom of this slit extends ina straight line from the grainsurface ,of the welt at the outer edge to the flesh surface of the weltat a point near the stitch receiving groove. It will be evidentyhowever;

made to extend more nearly parallel with the grain surface of the welt,1

While I consider-it preferable forthe reasons hereinbefore stated to usea knife which is adapted to form slits inthe welt obliquely disposed tothe surface of the'welt, it will be obvious that a knife adapted to formslits in the welt disposed at right angles to the surface of the weltmight be employed. The form of slits formed in the welt in such case isindicated in Figs. 17, 18, and 19, in which figures 36 indicates a weltstrip before being applied to a boot or shoe provided with slits 37disposed at right angles to the. surface of the Welt. In the particularform of slit indicated in these figures, the bottom of the slit extendsin a straight line from the grain surface of the weltat the outer edgeto the flesh surface of the welt at a point near thegroove in the .welt.

In Figs. 14, 15, and 16, I have indicated a modified form of knife, thecutting blade 38 of which instead of being arranged in the same lanewith the flat shankas in the knife illustrated in Figs. 11, 12, and 13is arranged at right angles to the shank. It will be evident that theblade of the knife can be arranged at any desired angle with relation toits shank, so that the slits produced in the welt may be disposed atright angles to the surface of the welt or at any desired angle ofinclination.

As I have stated, certain features of my invention are applicable to amachine for'operating upon a welt before it is applied to a boot orshoe, and in Figs. 8, 9, and 10 I have illustrated a form of worksupport which may be substituted for the work support 6 and which isadapted to support and guide a. welt strip. Referring to these figures,39 .indicatesthe support which may be clamped on the arm 7v of 'themachine'illustrated in Fi s.- 1, 2, and 3 by means of the clamping boIt8 in place of the support 6. The front edge'of the sup ort.39 isprovided with up turned guiding ugs 40 which with guides 41 and 42adjustably secured to the support 39 constitutes a guideway for the weltstrip. When this support is substitute/din the mas chine illustrated inFigs; 1, 2, and 3 for the support 6, the machine acts to feed and slitthe welt strip, the operation being the same as has been described.Forms of welt strips which are produced by the machine are-illustratedin Figs. 17 to 22. Such welt strips can be applied to a boot or shoe inthe same manner as an ordinary welt. When the ma chine is used tooperate upon welts before being applied to a boot or shoe, I prefer forthe reasons hereinbefore stated touse a welt slitting knife which willform slits in the welt obliquely disposed to the surface of the welt,and for the further reason that whenthe slits are so formed the weltcanbe fed through the welt guideof a welt sewing machine without anyliability of the edges of the slits catching on the gui( e.
